LAMIERINO MAGNETICO PER LA FABBRICAZIONE DI NUCLEI DI FERRO LAMELLATI PER MACCHINE ELETTRICHE STATICHE O DINAMICHE.

摘要

An inexpensive lamination for use in transformers and/or other static or dynamic electric machines has a metallic layer one side of which is provided with a coat of hardenable adhesive and the other side of which is provided with a coat of insulating material. At least the adhesive coat can contain particles of sand, glass, a metallic oxide or a synthetic plastic material; such particles act as distancing elements between the respective side of the metallic layer and an adjacent metallic layer. The two coats are applied simultaneously between an unwinding station for a web or strip of coherent metallic layers and a winding station for the freshly coated web or strip of coherent metallic layers.
